var attachments = message.Attachments; if (attachments.Any()) { foreach (var attachment in attachments) DownloadAttachment(attachment); } private static void DownloadAttachment(MimeEntity attachment) { if (attachment is MessagePart) { var fileName = attachment.ContentDisposition?.FileName; var rfc822 = (MessagePart)attachment; if (string.IsNullOrEmpty(fileName)) fileName = "attached-message.eml"; var path = Path.Combine(DIRECTORY, fileName); using (var stream = File.Create(path)) rfc822.Message.WriteTo(stream); } else { var part = (MimePart)attachment; var fileName = part.FileName; var path = Path.Combine(DIRECTORY, fileName); using (var stream = File.Create(path)) part.Content.DecodeTo(stream); } } |
